Physical and cognitive doping in university students using the unrelated question model (UQM): Assessing the influence of the probability of receivin…

2018

Study objectives: In order to increase the value of randomized response techniques (RRTs) as tools for studying sensitive issues, the present study investigated whether the prevalence estimate for a sensitive item π̂$_{s}$ assessed with the unrelated questionnaire method (UQM) is influenced by changing the probability of receiving the sensitive question p. Material and methods: A short paper-and-pencil questionnaire was distributed to 1.243 university students assessing the 12-month prevalence of physical and cognitive doping using two versions of the UQM with different probabilities for receiving the sensitive question (p ≈ 1/3 and p ≈ 2/3). Likelihood ratio tests were used to assess wheth…

Perceived tiredness among adolescents and its association with sleep habits and use of psychoactive substances

1997

This study investigated the variation in perceived tiredness among 11, 13 and 15-year-old Finnish adolescents (n = 4187). Additionally interrelationships between sleep habits, use of psychoactive substances (alcohol, tobacco and coffee) and perceived tiredness among 15-year-olds were examined. This study is part of an international, WHO-coordinated survey of school children's health and lifestyle (the HBSC Study). In Finland, research data represented the whole country. The data were collected in March-May 1994. Pupils responded anonymously to a standardized questionnaire during a class period. Subjective tiredness was very common and increased with age among adolescents. Perceived tirednes…

Drug use, family support and related factors in university students. A cross-sectional study based on the uniHcos Project data

2019

Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression mo…

Prospective relationships of ADHD symptoms with developing substance use in a population-derived sample

2011

BackgroundClinically ascertained reports suggest that boys and girls with attention deficit hyperactivity disorder (ADHD) may differ from each other in their vulnerability to substance use problems.MethodA total of 1545 Finnish adolescents were assessed for DSM-IV-based ADHD symptoms by their parents and classroom teachers using standardized rating scales at age 11–12 years. At age 14, substance use disorders and psychiatric co-morbidity were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism, providing DSM-III-R/DSM-IV diagnoses for Axis I disorders. At age 17.5, substance use was assessed by multi-item questionnaire.ResultsAlthough baseline ADHD symptoms were less…

Randomized response estimates for doping and illicit drug use in elite athletes.

2008

Abstract Background To date, there are estimates for the percentage of unknown cases of doping and illicit drug use in fitness sports, but not for elite sports. This can be attributed to the problem of implementing questionnaires and surveys to get reliable epidemiological estimates of deviant or illicit behaviour. Methods All athletes questioned were subject to doping controls as members or junior members of the national teams. In order to estimate the prevalence of doping and illicit drug abuse, the athletes were either issued an anonymous standardized questionnaire (SQ; n  = 1394) or were interviewed using randomized response technique (RRT; n  = 480). We used a two-sided z -test to comp…

Early-onset depressive disorders predict the use of addictive substances in adolescence: a prospective study of adolescent Finnish twins

2008

Aims  To explore the developmental relationships between early-onset depressive disorders and later use of addictive substances. Design, setting and participants  A sample of 1545 adolescent twins was drawn from a prospective, longitudinal study of Finnish adolescent twins with baseline assessments at age 14 years and follow-up at age 17.5 years. Measurements  At baseline, DSM-IV diagnoses were assessed with a professionally administered adolescent version of Semi-Structured Assessment for Genetics of Alcoholism (C-SSAGA-A). At follow-up, substance use outcomes were assessed via self-reported questionnaire. Findings  Early-onset depressive disorders predicted daily smoking [odds ratio (OR) …

Tobacco, Cannabis, and Other Illicit Drug Use Among Finnish Adolescent Twins: Causal Relationship or Correlated Liabilities?*

2010

Contains fulltext : 90566.pdf (Publisher’s version ) (Open Access) Objective: Among Finnish adolescent twins, we compared (a) a model that describes a direct impact of liability to tobacco use on cannabis and other illicit drug use with (b) a model that included a shared underlying liability for these substances. Furthermore, the extent to which genetic and environmental influences contribute to the covariation between liabilities to use these substances was examined. Method: Tobacco and illicit drug use were assessed at age 17.5 years. Twin data on 3,744 individuals were analyzed using standard biometrical methods. Two alternative multivariate models were fit and compared with Mx, a statis…

Perforated giant mycotic aneurysm of mitral valve in a drug-addicted young man: Rare complication of infective endocarditis

2017

Infective endocarditis (IE) affects patients at high clinical risk and may present as an acute and rapidly progressive, subacute or chronic infection. Transthoracic and transesophageal echocardiography represent the key diagnostic method in IE diagnosis. In particular, three-dimensional transesophageal echocardiography represents the imaging technique that allows to establish with adequate accuracy dimensions, shape, and localization of endocarditis vegetations. In our case, we show a huge vermiform mycotic aneurysm in an immunodeficient young drug-addicted man with severe mitral valve regurgitation and the additive value of three-dimensional transesophageal echocardiography in this specifi…

Smoking differently modifies suicide risk of affective disorders, substance use disorders, and social factors

2008

Abstract Background Although an association between smoking and suicide has repeatedly been shown, information about a modifying influence of smoking on other risk factors for suicide is lacking. Methods Axis I and Axis II disorders, sociodemographic factors, and tobacco use were assessed by a semi-structured interview including the Structured Clinical Interview for DSM-IV Axis I (SCID-I) and Personality Disorders (SCID-II) in 163 suicides (mean age 49.6 +/− 19.3 years; 64.4% men;) by psychological autopsy method and by personal interview in 396 living population-based control persons (mean age 51.6 +/− 17.0 years; 55.8% men). Results Smoking status (current smokers, lifetime non-smokers, a…
